Jim Simons' s Profile & Performance

Profile

In 1982, Simons founded Renaissance Technologies Corporation, a private investment firm based in New York with over $20 billion under management; Simons is still at the helm, as CEO, of what is now one of the world's most successful hedge funds.

Investing Philosophy

For over two decades, Simons' Renaissance Technologies' hedge funds, which trade in markets around the world, have employed complex mathematical models to analyze and execute trades, many of them automated. Renaissance uses computer-based models to predict price changes in easily-traded financial instruments. These models are based on analyzing as much data as can be gathered, then looking for non-random movements to make predictions.

"The advantage scientists bring into the game is less their mathematical or computational skills than their ability to think scientifically. They are less likely to accept an apparent winning strategy that might be a mere statistical fluke."

Sears Makeover Relevant to Online Shoppers
With a finger on the pulse of today’s shopper, Guru Edward Lampert has a gift for making retailers relevant to the ever-changing consumer. His retail re-visioning of Sears and Kmart is starting to pay off. Sears Holdings Corporation’s online businesses for Sears and Kmart grew 20% in the second quarter of 2013, year-over-year. Lampert’s brainchild, the Sears ‘Shop Your Way’ membership program, generated more than 65% of the revenues at Sears Domestic and Kmart during the second quarter, compared to around 55% in the same quarter a year ago. But despite e-commerce growth, Sears Holdings reported an operating loss of $51 million in the second quarter of 2013, after a loss of $103 million in the second quarter of 2012. Read more...

How I Used "One Up on Wall Street" to Guide Me Through Our Features--New and Old Jim Simons,Joel Greenblatt - How I Used
The very first book I read about investing in the market was One Up on Wall Street by Peter Lynch. I would honestly highly recommend this book to anyone who is new to the market and feels like a little shrimp lost in a huge ocean. Naturally, you want to listen to your friends and what companies they invest in, or take a look at what stocks are most talked about in the news. You may even feel like playing it safe would be to invest in the big name companies, but one thing Lynch says at the beginning of the book is that there are no real “experts” in the market. More...
